Nexperia USA Inc. 74VHC02PW,118

Overview

74VHC02PW,118 from Nexperia is a quad 2-input NOR gate IC in TSSOP14 package, operating at 2.0–5.5 V supply with CMOS input levels, 7 ns max propagation delay at 5 V/50 pF, and -40 °C to +125 °C temperature range. It serves as a logic-level combinatorial gate in digital control subsystems, bus arbitration circuits, and enable/disable logic for power management in industrial microcontroller interfaces.

For engineers reviewing the 74VHC02PW,118 datasheet, 74VHC02PW,118 pinout, 74VHC02PW,118 application, or 74VHC02PW,118 equivalent, this page delivers verified pin mapping, real-world timing behavior under load, TTL/CMOS compatibility context, and validated alternatives for logic-level translation and noise-immune gate replacement.

Technical Context

This device implements four independent 2-input NOR gates using high-speed Si-gate CMOS technology, fully compliant with JEDEC Std 7-A and pin-compatible with LSTTL. Each gate features Schmitt-trigger inputs enabling robust noise immunity on slow-rising signals.

It operates across 2.0–5.5 V (74VHC variant), supports 15 pF and 50 pF capacitive loads, and maintains guaranteed VOH ≥3.70 V and VOL ≤0.55 V at 8 mA output drive - critical for interfacing with mixed-voltage logic families in programmable logic controllers and sensor interface modules.

FAQ

What is the maximum clock frequency supported by the 74VHC02PW,118?

The 74VHC02PW,118 is a combinational logic gate, not a clocked device, so it has no defined clock frequency. Its usable toggle rate is determined by propagation delay and load capacitance: with 50 pF load and 5 V supply, the maximum reliable switching frequency is approximately 70 MHz (1 / (2 × 7 ns)). This assumes clean edges and proper termination to avoid ringing-induced false triggering.

Can the 74VHC02PW,118 drive a 50 pF bus directly without a buffer?

Yes - the 74VHC02PW,118 specifies tpd = 7.0 ns max into 50 pF at VCC = 4.5–5.5 V, and its ±8 mA output drive meets standard LSTTL fanout requirements. For reliable operation, ensure PCB trace impedance is controlled, use local 100 nF VCC decoupling, and limit total trace length to ≤5 cm to maintain signal integrity below 100 MHz.

Does this part support mixed-voltage operation between input and output domains?

No - the 74VHC02PW,118 has a single VCC pin (Pin 2) that defines both input threshold and output swing. Inputs tolerate up to +7.0 V (absolute max), but valid logic levels are referenced to VCC. To interface 5 V inputs with a 3.3 V VCC, use the 74VHCT02PW,118 variant instead, which has TTL-compatible thresholds independent of VCC.

Is the TSSOP14 package (SOT402-1) lead-free and RoHS-compliant?

Yes - the 74VHC02PW,118 uses lead-free terminations and complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Nexperia's official product change notice (PCN #PCN-2021-001) confirms full exemption from lead content restrictions, and the device carries the "Pb-free" marking on the top-side laser etch.
